Title: Hydrocarbon copolymers and their method of preparation
IPC: C08F2/38
Filed: 1957-07-17
Abstract: The invention comprises a copolymer of at least one aliphatic mono-olefin and an unsaturated bridged-ring hydrocarbon which contains at least two double bonds.  The copolymer may also contain further aliphatic olefin monomers and may be made by copolymerizing in the presence of a surface-active catalyst.  The mono-olefins preferably comprise a major proportion of the copolymer and may be ethylene, propylene, butene-1, isobutene, pentene, hexene, heptene, octene, nonene or decene and these may contain linear or branched chains.  The preferred bridgedring hydrocarbons contain 7-10 carbon atoms and a bridge of 1-2 methylene groups and may be bicyclo (2, 2, 1) hepta -2, 5-diene; bicyclopentadiene (i.e. 1, 4-endomethylene hydrind -2, 6-diene); tricyclo-or tetracyclo-pentadiene or bicyclo (2, 2, 2) octa- 2, 5-diene or similar derivatives of bicyclo (3, 2, 1) octane, bicyclo (3, 3, 1) nonane or bicyclo (3, 2, 2) nonane, all containing at least two double bonds.  The copolymerization may occur in the presence of a solvent such as butane, hexane, heptane, octane, petroleum ether, kerosene, cyclohexane, methyl cyclohexane, benzene or toluene.  The surface-active catalyst may be a mixture of a compound of a heavy metal of the A sub-Groups IV to VII or Group VIII, e.g. TiCl4 or VCl4, together with an organometallic compound, e.g. Al, triisobutyl, or a metal hydride and may be supported on a finely divided carrier such as cryolite, silica or carbon black.  The catalyst may be added incrementally and may be destroyed after the polymerization with methanol or isopropanol.  The monomers may be added incrementally and the polymerization may be carried out at low temperatures, e.g. -60 DEG  C.  The polymer may be washed with methanol, which may contain an antioxidant such a b -naphthylamine. The examples describe the preparation of copolymers derived from 3 or 4 monomers.  The polymers can be vulcanized with sulphur, and the cure ingredients may be carbon black, zinc oxide, stearic acid and cure-promoters.

Abstract: Mineral lubricating-oils suitable for use at high temperatures, e.g. 150--200 DEG  C. or higher, are stabilized by the addition of an oxidation inhibitor comprising an oil-soluble compound with an aromatic nucleus having directly attached thereto both an inhibitor group and a stabilizer group comprising an oxygen, sulphur, selenium or tellurium atom attached to the nucleus in ether form.  Specified inhibitor groups are hydroxyl, amino, di- or polysulphide, -selenides and -tellurides, and aromatic mercaptans.  An addition of about 0,1 per cent is suitable.  In an example, a mineral white oil, prepared by heavy treatment with fuming sulphuric acid, is stabilized by an addition of parahydroxy phenyl normal amyl sulphide.

Title: Improvements relating to pneumatic fluid pressure motors
Inventor: MORAGHAN TERENCE MICHAEL
IPC: B60S1/10
Filed: 1947-08-15
Abstract: 638,524. Engine valve gear; vacuum engines. TRICO-FOLBERTH, Ltd. Aug. 15, 1947, No. 22773. [Classes 122(ii), 122(iii) and 122(iv)] In a valve gear for a pneumatic fluid motor, particularly suitable for operating a windscreen wiper, the pressure differential on the piston is reversed by a valve operated by the motor and normally moved between two operating positions but also capable of being moved into a third position thereby causing the valve operating means to be disconnected and the pneumatic fluid pressure differential to act on one side only of the piston which then makes an abnormally long stroke and is brought to rest. A disc valve 19, 'pivotally mounted at 7, has valve recesses 20 and 31 on its underside and is oscillated by a projection 16 on a kicker plate 6, also pivoted at 7, operated by a trigger mechanism comprising levers 1 and 9 and springs 12 and 14, and actuated by the piston rod 4 oscillating lever 1 about a pivot 2. For normal working the valve 19 oscillates between a fixed stop 24 and a movable stop 25 in the position shown in Figs. 1 and 2 and alternately places ports 21 and 23, leading to the right- and left-hand ends of the motor cylinder respectively, in communication with a port 22 connected to. a source of suction-the port 32, and the port 23, when uncovered by the valve disc 19, being open to atmosphere. To cause the piston to make a longer stroke and then come to rest-as required for parking a windscreen wiper-the movable stop 25 which is attached to a gear wheel 26 operated by a rack 27. is moved in an arcuate slot 28 until it abuts a spring 29 (Fig. 5) and thus allows the valve 19 and kicker 6 to rotate further in a clockwise direction, a projection 33 on the kicker acts as a cam on lever 1 and lifts its free end clear of the piston rod. Ports 21 and 22 are then in communication through recess 31 and port 23 is connected with the atmosphere through recess 20 and slot 28 thereby causing the piston to move to the right until stopped by contact with the cylinder end or otherwise. To work a windscreen washer the stop 25 is moved against the action of spring 29 to the end of slot 28 thereby allowing valve 19 to rotate still further and connect the source of suction with the windscreen washer through port 22, a recess 34 and a port 35.

A positive balk for a single or double positive clutch 3, 9, frictionally synchronized by a cone 10, comprises a stop-peg 14, slidable radially between guides 13 on the freely rotatable cone 10, and having its opposite ends cylindrically curved in planes at right-angles, so that, under the pre-synchronous drag-torque of the cone 10, its inner end 15 rides radially up a curved surface 17 on an inner member 5 splined on the shaft 1, Fig. 2 position, whereby its outer end 16 obstructs axial movement of a curved abutment 20 in the outer positive clutch sleeve 9 splined on the shaft member 5. Attainment of synchronism causes axial clutch-engaging thrust to push the stop peg 14 inwards, releasing the clutch sleeve 9 for positive engagement with the clutch teeth 3 of a freely-mounted wheel 2. The abutment 20 may, as shown, be formed by a spline-gap in the clutch-sleeve 9. A spring-ball 23 locates the disengaged position, and the stop-peg 14 may be outwardly spring-loaded. The synchronizing cone 10 is retained on the shaft-member 5 by a circlip 11 and its free relative circumferential movement is limited by clearance engagement of the balk-peg guides 13 in a recess 18 in the shaft-member 5. In the double-clutch form, Figs. 7 and 8, not shown, separate synchronizing cones span a central rib on the shaft member and are held together by bolts.

[Class 75(i)] A liquid fuel burner has two bowl-like members 5 and 1 arranged one within the other to provide a fuel vaporizing space 6 therebetween with an annular opening 8 at the rim region and has an apertured plate 16 spaced above the bowl-like members and extending horizontally on all sides thereof beyond the rim; the arrangement is such that the combustion air passes from below and through the space formed between the underside of the plate 16 and the tops of the bowl-like members 5 and 1 and thence upwards through the aperture in the plate 16. The bowl 5 is held within and spaced from the bowl 1 by a spigot 10 of rectangular or similar cross-section fitted into a circular orifice of bowl 1 and by lugs 7 on the outer spherical surface of bowl 5 or the inner spherical surface of bowl 1. The radius of curvature of the outer surface of bowl 5 is greater than that of the inner surface of bowl 1. The area of the air space formed below the underside of plate 16 is varied by raising a sleeve 12 the upper end of which is formed with a frusto-conical flange 15. This is effected by moving lever 14 to rotate and raise the sleeve 12 through a helical groove and pin connection 13. The bowls 1 and 5 may be spherical, as shown, or of any other curved surface, and may have a cross-section other than circular. In an alternative arrangement, Fig. 2 (not shown), forced feed air is supplied by a fan arranged below the bowls and a flame spreader is inserted within the upper bowl. The inner bowl 5 may also be provided with a number of apertures. Starting is effected by igniting a small quantity of fuel and waste placed in the inner bowl 5.
